Tom has done a lot of work on his master slides. He changed the size, and he's using a new font. The size should not give you any problems, but you may have to install the font on your computer to see the slides the way Tom intends them to look. The font is called One Stroke Script. You can read them without that font, they'll just look different. Here's the file: Working Master 2006.
Before blogging became all the rage, Tom was posting book reviews and Observations (essentially early blog posts) to this site. You can find the archives below.
